Boxing legend Roy Jones Jr. is going to trade punches with a former UFC champion – but it’s not going to be Anderson Silva.

Jones Jr. and Quinton “Rampage” Jackson will meet in a boxing match on pay per view at the end of the year, according to a report by MMAjunkie.com. Jackson is currently under contract with Viacom, the parent company of Bellator MMA. It’s unclear how the bout will be branded, but the plan is to go up against UFC 168, which is headlined by title fights between Silva and Chris Weidman and Ronda Rousey and Miesha Tate.

A date and weight class for the bout are unclear. A Jackson representative said they have been talking to Jones Jr.’s people “for over seven months.” That’s right around the time Jackson’s contract with the UFC expired, following a fight with Glover Teixeira in January.

The 35-year-old Jackson, a former UFC light heavyweight champion, signed with Viacom last month. With the massive media conglomerate, “Rampage” will fight MMA for Bellator, appear for TNA Impact pro wrestling and star in his own reality show. The door has also been opened for Jackson to appear in movies. He starred as B.A. Baracus in the 2010 film “The A-Team.”

The 44-year-old Jones Jr., who is 56-8 as a boxer and a former four-division champion, flew to Las Vegas earlier this month to talk to UFC president Dana White about possibly fighting Silva. But Silva lost his title fight that night to Chris Weidman and that idea was put on hold. White told The Post that if Silva won, he would have considered a matchup between him and Jones Jr.

Jackson told The Post in June that one of his regrets is that he never competed in a pro boxing match. Jones Jr. was willing to meet Silva in an MMA fight, but this potential throwdown with “Rampage” will be on his turf.

Both men remain wildly popular and were the best in the world at what they do for a time. But now they are past their primes in their respective combat sports. Jackson has lost three MMA fights in a row, while Jones Jr. hasn’t beaten a significant boxing opponent in four years.
